  1. I'll start at 400V and work from there.
  2. We might run it at 20mA or even higher. Plenty of heatsinking needed....
  3. Only up to 600V though. Don't try them in the BH...
  4. Well we've been using them in the KGSSHV for a few years now and the 2SA1486 would always work as a replacement too.
  5. The gain on the KGST is the same as on all the other 'stat amps we've done. Volume pot impedance doesn't matter so how much voltage are you feeding it?
  6. That's pretty much what it is. A KGSSHV with the last stage removed and the gain stage beefed up.
  7. This stuff belongs on HF. Now for something that belongs here... something new... The ever so elusive Carbon...
  8. It's actually Rauðafellsgjá but I guess that's about as much gobbeldy gook... It's funny how related English and Icelandic are but the pronunciation is so different.
  9. I could throw in a loaf of sourdough...
  10. Use Vishay's and lift them off the board which does the same thing.
  11. I've pretty much cleared out all the Japanese sellers at this point but you don't need that many. Use KSA1156's in the front end so you just need a handful per amp.
  12. No capacitors or resistor issues that I'm aware of. These are generic parts so there are always subs.
  13. I sent them an offer for one so we'll see. Expensive shipping given it's next door and less than 1kg...
  14. The 2SA1486 is perfect for this role and so is the STN9360. If you have a KSA1156 that measures well above 600V then it will work too. Just remember the pinout difference.
  15. Apparently pigs can fly....
  16. Not a chance in hell that those are real. Bdent has the real deal but they are not cheap. On the new boards these will be swapped out for STN9360's.
  17. I wouldn't use the KGSSHV psu as it just doesn't like that load. No mods possible with that PSU board which is why we are slowly working on a new one.
  18. Try switching to the 3GS/4... it is just comically small in comparison.
  19. The teflon male plug is certainly real even though they were not cheap. The first prototype is on my HE90: Neutrik XLR male pins are perfect for this role. Not sure if Kevin has any more as only a few of these were made.
  20. Indeed, the CCS isn't active as the LED is missing. Also the soldering on the feedback selector is suspect and with the local resistors also in place that could short and cause problems.
  21. That reminds me too much Single Power so don't do that... No caps on these but then again the PSU is 10mm from the amp boards.
  22. Something is blown or shorted. Also the LV supply is kinda high, the 7x15 regulators should never be that much out of spec.
  23. The Russian Blue Hawaii (FluxLab) uses a lot of adhesive which tends to get not so adhesive when it warms up. Top tip, glue and a 200W space heater doesn't mix. Funny enough that BH and it's sister amp run pretty cool for the breed. Much cooler than the BHSE for instance.
  24. Adhesive would be very much in the vein of Single Power so I use screws.
  25. Nope, busy building these... Finishing up the last of my old BH stuff. The black one is running in now.
